Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on the cooling system.

2. Replace Coolant

Tools Required: Coolant funnel, drain pan
Drain the old coolant from the radiator by opening the drain valve.
Flush the radiator with clean water to remove any debris.
Refill the radiator with the manufacturer-recommended coolant mixture.

3. Replace Thermostat (if faulty)

Tools Required: Socket set, gasket scraper, torque wrench
Remove the thermostat housing by unscrewing the bolts.
Take out the old thermostat and clean the mating surfaces.
Install the new thermostat in the correct orientation and reattach the housing, torquing to manufacturer specifications.

4. Repair or Replace Radiator Fan (if defective)

Tools Required: Multimeter, socket set
Disconnect the electrical connector from the radiator fan.
Use a multimeter to test the fan motor for continuity.
If defective, unbolt the fan assembly and replace it with a new unit.

5. Reassemble and Test

Reconnect the battery and ensure all components are secure.
Start the engine and allow it to reach operating temperature while monitoring the temperature gauge and radiator fan operation.
